The LCL extends the Width if possible.
A fixed Width can be set with Constraints.Min/MaxWidth or using Anchors.
The label will extend the Height if WordWrap is true and the Width is

That means the LCL does not need any special rule for TLabel.

This has also the advantage that a LCL wordwrapped TLabel can
resize in both directions.

So, the LCL is more consistent and more powerful. So I would prefer to
break Delphi compatibility here.
